Indeed, the lowering of standards for pollutants in drinking water requires the development of new technologies and devices. In this context, gated sensory nanoparticle systems for selective and sensitive recognition of targets such as heavy metal ions, small molecules or oligonucleotides are excellent candidates[1,2]. Provided that such sensory delivery systems are highly porous nanoparticles loaded with indicator dyes and capped with bulky stoppers that can be uncapped only by the designated analyte, an integration with a microfluidic tubing system designed for droplet-assisted liquid-liquid extraction enable separation of released from still particle-confined dye by phase-transfer extraction and subsequent selective detection by fluorescence. The incorporation in a simple microfluidic tubing system is an innovative way towards the realization of a sensor for trace analysis of target molecules in real time.
